Population Flashcards
What is population
The term population means the number of inhabitants who live in a particular country or region.
Total land area is ________
510 million square km
Humans occupy only ______ of the entire earths land area
64 million square feet km
Hiw has the population of a country led to exacerbating the environment
Biodiversity loss, climate change, pollution, deforestation, water and food shortages have all been exacerbated (made worse) by the huge and our ever-increasing numbers leading to ever-increasing consumption.
Name the animals that have declined by 68 percent
wild vertebrate animal populations like elephants, tigers, orangutans, wolves, leopards, foxes, polar bears and so on declined by 68 per cent.
What is oceania
Oceania consist of Australia, New Zealand and the Pacific Islands of Fiji, Papua New Guinea, Vanuatu, Samoa, etc.
India has the largest population of ________ followed by china with _________
1.428, 1.425
What is birth rate?
Birth rate is number of live births per year per 1,000 of the population. The formula for calculating birth rate is:
What is death rate?
Death rate is number of deaths per year per 1,000 of the population. The formula for calculating death rate
What is life expectancy
Life expectancy is the number of years that a person is likely to live.
What is population density
Population density refers to the number of people living in a unit area of space, such as a square kilometre.
High birth rate leads to an ______ in population and high death rate leads to a _____ in population
Increase decrease
why have death rates declined?
Death rates declined as new developments in agricultural practices and transportation technology increased the food supply and reduced the danger of famine. Public health and living standards had improved due to new technologies and industrial development.
Name the factors that have improved life expectancy in india
- Improvement in healthcare and hygiene
- improvement in sanitart conditions particularly in rural areas (Schemes like
Swacchh Bharat)
3.Improvement in education standards with more schools being built. - Improvement in Mid-Day Meal Scheme for schoolchildren who are provided more nutritious diet.
- Improvement in medical care with more healthcare centres and free vaccinations for diseases such as cholera, tuberculosis, Covid-19 etc. leading to better control of epidemics.
- Better flood control and famine management.
- Better management of natural disasters
What is immigration
The process of coming to live permanently in another country that is not one’s own is called immigration (into a country).
What is emigration
The process of leaving one’s own country to go and live permanently in another country is called emigration (where people exit a country).
What is an opem door policy
When a country is highly urbanized, the birth rate tends to rise and death rates tend to fall (GR)
. There is an increase in the birth rates as people have more access to medical care in cities than in rural areas, and hence, infant mortality falls and the birth rate rises.
Death rates decline in urban areas because of better medical and education services, and more reliable food supplies. This is often not the case in remote rural areas, so death rates fall in urban areas.
How does agriculture help in increasing population
. The mechanization of agriculture has freed up workers from the farms.
It has encouraged industrialization which needs lots of workers.
It tends to promote high birthrates. Moreover, the increased agricultural production has reduced the deaths due to famine, thereby causing the population to grow
How does education impact the growth of population
. Simple programmes in hygiene can reduce death rates, while family planning programmes can reduce birth rates.
The governments in various countries have launched massive awareness campaigns on population growth and help people to plan families.
Eventually, the educational and awareness levels of people also have an impact on the growth of the population.
How does the topography of a place effect its climate
Population also grows in areas where the land is flat and is cultivable and water is available in plenty for both agricultural and domestic purposes.
The cities that grow on the banks of rivers have a large population.
How does the climate of a place effect the population
The climate of a place is also an important factor in determining the population growth.
If the climate is pleasant, it will attract
population. Climate, relief features, soil in quality and proximity to natural resources th have influenced human life.
How does transport and communication help the growth of population
Transport and Communication
Population of a place grows if it is easily accessible by various kinds of roads, rivers and railway lines.
Communication systems like internet, phone and post is essential in today’s living and so places with these facilities have more population.
How does employment opportunities encourage population growth
Population of a place grows if there are prospects for employment.
Mines and industries in the area are potential sources of employment and therefore, encourage population growth.
What is overpopulation
Overpopulation is a very undesirable condition where the number of people in a particular area exceeds the availability of resources to meet the needs of all the people in the area.
